The 72 VDC coil with a pick-up hold of 0.7x rated value means it pulls in reliably on a sagging DC bus, and the 80–100 ms dropout delay gives the PLC time to sequence downstream contactors off before the main drops. Operating range spans -40 to +70 °C ambient, so it lives in unheated enclosures or next to a motor without a heater — the storage band is even wider at -55 to +80 °C. ## Screw fixing and mounting flexibility — panel integration notes Fastening is screw fixing through an 11 mm hole — no DIN-rail clip on this variant, so budget for a backplate or sub-panel with the single mounting hole centred. ## Terminal wiring capacity and auxiliary contact provision An auxiliary switch is included, so you get at least one NO/NC feedback pair for the PLC input without adding a separate side-mount block.","metaTitle":"Siemens 3RT1466-6XJ46-0LA2 SIRIUS Contactor, 156 A at 480 V","metaDescription":"Siemens SIRIUS 3RT1466-6XJ46-0LA2 contactor, Size S10 frame, rated 156 A at 480 V AC-1. 72 VDC coil, screw fixing, -40 to +70 °C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"Depth":"202 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"145 mm","at DC":"80 ... 100 ms","title":"3RT1466-6XJ46-0LA2","Height":"210 mm","Upwards":"10 mm","Forwards":"20 mm","Downwards":"10 mm","Arcing Time":"10 ... 15 ms","At The Side":"10 mm","Rated Value":"72 V","description":"power contactor AC-1 400 A / 690 V / 40 °C 3-pole, Uc: 110 V DC (0.7-1.25) PLC input 24-110 V DC drive: electronic auxiliary contacts 2 NO + 2 NC main circuit: busbar control and auxiliary circuit: screw terminal extended rated condition railroad IEC 60077","Initial Value":"0.7","During Storage":"-55 ... +80 °C","Number Of Holes":"1","Type Of Voltage":"DC","at AC-1 maximum":"600 1/h","at DC-1 maximum":"350 1/h","lifecycle_stage":"current","Auxiliary Switch":"Yes","During Operation":"-40 ... +70 °C","Fastening Method":"screw fixing","Full-Scale Value":"1.25","Diameter Of Holes":"11 mm","Mounting Position":"with vertical mounting surface +/-90° rotatable, with vertical mounting surface +/- 22.5° tiltable to the front and back","Size Of Contactor":"S10","Solid Or Stranded":"2x (0,5 ... 1,5 mm²), 2x (0,75 ... 2,5 mm²), max. 2x (0,75 ... 4 mm²)","Product Brand Name":"SIRIUS","Product Designation":"Contactor","at 24 V rated value":"6 A","at 48 V rated value":"2 A","at 60 V rated value":"2 A","Of Contactor Typical":"10 000 000","at 110 V rated value":"1 A","at 125 V rated value":"0.9 A","at 220 V rated value":"0.3 A","at 230 V rated value":"6 A","at 400 V rated value":"3 A","at 480 V rated value":"156 A","at 500 V rated value":"2 A","at 600 V rated value":"144 A","at 690 V rated value":"132 kW","Design Of The Product":"With extended operating range","Instantaneous Contact":"2","Side-By-Side Mounting":"Yes","For Auxiliary Contacts":"18 ... 14","Width Of Connection Bar":"25 mm","For Main Current Circuit":"screw-type terminals","at 220/230 V rated value":"60 hp","at 460/480 V rated value":"125 hp","at 575/600 V rated value":"150 hp","Relative Humidity Minimum":"10 %","at maximum Ith rated value":"240 mm²","Of Main Circuit Rated Value":"8 kV","Thickness Of Connection Bar":"6 mm","at AC-3 rated value maximum":"690 V","at maximum AC-1 rated value":"240 mm²","at AC-2 at 400 V rated value":"75 kW","Substance Prohibitance (Date)":"09/06/2016","Design Of The Surge Suppressor":"with varistor","at AWG cables for main contacts":"2/0 ... 500 kcmil","Of Auxiliary Circuit Rated Value":"6 kV","For Auxiliary And Control Circuit":"screw-type terminals","Function Module For Communication":"No","Product Function Bus Communication":"No","With Type Of Assignment 2 Required":"gR: 500 A (690 V, 100 kA)","closing power of magnet coil at DC":"580 W","holding power of magnet coil at DC":"3.4 W","With Type Of Coordination 1 Required":"gG: 500 A (690 V, 100 kA)","at AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","operational current at AC-12 maximum":"10 A","number of NC contacts for main contacts":"0","number of NO contacts for main contacts":"3","reference code according to IEC 81346-2":"Q","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Number Of Poles For Main Current Circuit":"3","voltage at PLC-control input rated value":"24 V","Product Function Short Circuit Protection":"No","mirror contact according to IEC 60947-4-1":"Yes","number of NC contacts for auxiliary contacts":"2","number of NO contacts for auxiliary contacts":"2","Type Of Voltage Of The Control Supply Voltage":"DC","up to 40 °C according to IEC 60077 rated value":"400 A","up to 70 °C according to IEC 60077 rated value":"330 A","Limited To 1 S Switching At Zero Current Maximum":"5 524 A;
